What is Error Handling?
Error handling is defined as the process or mechanism in programming languages for identifying, catching, and responding to exceptional situations that may occur during the execution of the program. So basically, in simple words, it is the process of identifying the errors in the program and throwing them out without affecting the program’s output.
- There can be various types of errors or they arise due to various reasons like hardware failure, programming mistakes, incorrect input, etc, so error handling is used to identify and neglect these types of errors.
- Proper error handling is very essential for creating robust and reliable software.
- In Objective-C error handling is used to write robust codes, here error handling is mostly implemented by using the Cocoa error-handling pattern or technique to identify the errors in the written code.
- This method completely relies on the use of NSError objects in the program.
- Exception handling is another method used for error handling there we use it to try and catch the block to identify the error in the program and then throw the error out of the program without affecting the code.
